{"version":"1.0","type":"rich","title":"Activity_7 Q_1","description":"This example shows a pie chart of five books and their average ratings, using a static dataset embedded in the code. The chart is rendered as an SVG using D3 v7, with pie slices generated by the `d3.pie` and `d3.arc` functions, colored via `d3.scaleOrdinal` and `d3.schemeCategory10`. Labels are placed at each slice’s centroid, and a legend with color swatches and rating values appears on the right. The SVG is styled with a white background and subtle shadow.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3cc69d46145249a592305ea7061b662d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
